Driving method of bistable display device

Abstract

The invention relates to a driving method of a bistable display device, which is used for driving the bistable display device. The bistable display device comprises multi-column and multi-row pixels, a time sequence controller and a source driver. The time sequence controller is used for providing control signals which respectively correspond to a forward high voltage, a reverse high voltage and a grounding voltage to the source driver, and the source drivers is used for driving the pixels by the voltage which corresponds to the control signals. The driving method comprises the following steps: if the source driver provides the forward high voltage to one of two pixels when continuously driving the two pixels on the adjacent two columns in any row, then only the forward high voltage or the grounding voltage can be provided to the other one of the two pixels.

Description

technical field [0001] The invention relates to a driving method of a display device, in particular to a bistable display driving method capable of improving the image display quality of the bistable display. Background technique [0002] At present, the application of thin displays is becoming more and more common, bringing great convenience to life. Among them, the electronic paper display is regarded as a flat display technology of the next generation display technology because of its portability and low power consumption. [0003] The electronic paper display has two substrates, between which positively charged black particles, negatively charged white particles and a solvent are injected. One of the substrates is a transparent substrate, and the area to which a positive voltage is applied appears white due to the attraction of negatively charged white particles, and the area to which a negative voltage is applied appears black due to the attraction of positively charge...

AI Technical Summary

Problems solved by technology

After testing, it was found that during the image update process, when the source driver continuously drives two pixels on two adjacent columns in any row, if a forward high voltage is provided to one of the pixels, and a reverse high voltage is provided If the voltage is applied to another pixel, it will easily cause excessive power consumption caused by the large-scale switching of the output voltage of the source driver, so that the image of the bistable display will have abnormal display conditions, such as chromaticity and brightness interference (crosstalk). ), bandmura, etc., thereby reducing the image display quality of the bistable display

[0006] This shows that the above-mentioned existing bistable display driving method obviously still has inconvenience and defects in method and use, and needs to be further improved urgently.

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and the general method has no suitable method to solve the above-mentioned problems. This is obviously related. The problem that the industry is eager to solve
